提出了一种具有条件访问控制的广播场景下密钥管理的新方法。它采用了重新配置的概念，并且它基于底层结构的集合——在每个时刻，使用集合中的一个结构来更新会话密钥，以便将更新的通信开销降至最低。接收方有一组固定的加密密钥，在一般情况下，这些密钥中的每一个都扮演由所采用的底层结构决定的不同角色。
A novel approach for the cryptographic keys management in the broadcasting scenario with a conditional access control is proposed. It employs the reconfiguration concept, and it is based on a collection of the underlying structures - at each instant of time a structure from the collection is employed for updating the session key so that the communication overhead of updating is minimized. A receiver has a fixed set of cryptographic keys and in a general case, each of these keys plays a different role determined by the employed underlying structure.
